I am going threw the same thing now. At work I kept feeling like I was going to fall over and have been having these bad headaches and stay tired. I went to the doctor they first gave me this pill that dissolve on your tongue but it didn't do any good for my head and then they gave me a shotand it made it go away. But on Mar. 20 I have to go and get a Mri done. Write me back and I'll let you know how it went.
